RockMod Match history and forecast production accurately RockMod® performs multiple stack (AVO/AVA) geostatistical reservoir characterization to produce multiple highly detailed models through tightly integrating disparate data across all pertinent geoscience domains. The outcome is accurate reservoir models in depth for prediction of field reserves, fluid flow patterns, and future production. Another value it provides is a reliable basis for quantitative measure of uncertainty. RockMod is relevant where dual or triple parameters like P-Impedance, S-Impedance and Density are needed to distinguish the facies of interest. Excellent match in the prediction of monthly production rate from the simulator (Black line) versus the historic data (Purple dots) with no use of Porosity modifiers in the simulation model. Projected ultimate recovery for various production scenarios through 2040. Presented at the 2008 Petroleum International Exhibition and Conference held in Abu Dhabi, UAE, 3-8 November 2008.
